Application filed September 13, 1912. Serial No. 720,186.

To all whom it may concern:

Be it known that we, ARTHUR Gnonon BoozER, Jr., and GEORGE HILL, citizens of the United States, residing, respectively, at Greenville, Greenville county, and Tucapau, county of Spartanburg, in the State of South Carolina, have invented certain new and useful Improvements in Doifing-Machines, of which the following is a specification.

This invention relates to doliing machines arranged to travel along the sides of spinning machines for dotting the filled bobbins from the spindles and supplying empty bobbins thereto.

One of the objects of the invention is to provide an improved magazine and feeding means for the empty bobbins. I

Another object is to provide an improved mechanism for driving the dotfing machine.

Further objects and advantages of the invention will be set forth in the specification and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of the upper portion of a dotling machine embodying the features of our invention, the figure also showing a portion of a spinning frame. Fig. 2 is a side elevation of the lower portion of the doffer and the adjacent part of the spinning frame. Figs. 3 and 4 are front elevations of the upper and lower portions of the dofier, respectively. Fig. 5 is a top plan view showing the magazine. Fig. 6 is a horizontal sectional view through the lower portion of the dofier illustrating a portion of the driving means. 'Fig. 7 is a side elevation of a spinning machine with parts broken out and illustrating a driving means employed in connection with the doiiing machine herein shown. Fig. 8 is a top plan view of the spinning frame with parts broken out, and illustrating the driving means. Fig. 9 is a fragmental end elevation of the spinning frame and the driving means.

The embodiment of our invention which we have herein shown by way of example comprises a framework consisting of sides 10, a base 11 connecting the lower portions of said sides, a horizontal table 12 at the upper ends of said sides, and a cross-piece 13 extending between the sides near their middle portion. When the doffer is not in association with the spinning frame, it rests upon rollers 14: mounted in the base 11. The bolster rail a of the spinning frame has a guide rail 15 fixed to its upper flange, upon which guide rail a pair of grooved rollers 16 upon the doffer is arranged to travel, said rollers supporting the doft'er upon the spinning frame clear of the floor. The rollers 16 are fixed upon short shafts 17 (Fig. 4:) which are rotatably mounted in eccentric bearings 18 carried in supports 19 upon the sides of the framework. A handle 20 fixed to one end of the bearings 18 provides means for rotating the bearings, after the rollers have been associated with the upper edge of the guide rail 15, to raise the doii'er and bring a toothed driving wheel, to be later described, into engagement with its rack. Each of the bearings 18 is provided with a lug 21, and these lugs are connected by means of a link 22, to provide for simultaneous movement of the bearings. A latch handle 23 carried by the handle 20 is arranged to operate a locking pin 24 which holds the bearings 18 in their adjusted positions. A pair of rollers 25 carried by the sides 10 are arranged to bear against the lower flange of the bolster rail a.

In the present instance the dofler is driven by means carried by the spinning frame. This means comprises a shaft 27 (Fig. 2) mounted upon one end of the spinning machine, said shaft being driven from the main shaft 28 of the machine through the medium of a diagonal shaft 29 having at one end a bevel pinion 30 meshing with a bevel gear 31 fixed upon said main shaft of the spinning machine, the other end of said diagonal shaft having a bevel pinion 32 meshing with a pair' of opposite bevel pinions 33 upon the shaft 27. Each of the latter pinions is provided with a clutch member 34 arranged to be engaged by one of two clutch members 35 slidably mounted upon the shaft 27 and rigidly connected by a crosshead 36. A vertical shaft 37 has at its lower end a crank-arm 38 pivoted to one end of the crosshead 36, the upper end of said vertical shaft having a handle 39 thereon for rotating it. When said handle is operated, the clutch members 35 will be moved into engagement with their complementarv members 34 for driving the shaft 27 in opposite directions.

mounted upon said end of the spinning frame is a bracket 44 having a pair of small sheaves 4L5 thereon over which one run of the cable extends." An angular arm 46 fixed to the tiltable bracket 44 carries a weight 47 which tends to swing saidbracket and the sheaves to keep the cable taut, as is clearly shown in Fig. 9.

The means provided on the dofling machine for engaging the driving cableis constructed as follows: A bearing bracket 50 (Fig. A) carried upon the base'll of the framework has rotatably mounted therein a horizontal shaft 51 upon the rear end of which is fixed a driving sheave 52. A pair of arms 53, pivoted upon the shaft 51, carry at their outer ends sheaves 54 arranged to overlie the cable 42. Said arms .53 are adapted to be swung downwardly to carry the cable into engagement with the driving sheave 52 bymeans of an arm fixed on a shaft which is mounted in a bracket 56, said arm being connected to the arms 53 by short links 57. Another arm 55 fixed on said shaft is connected by means of a link 58 with an arm 59 rigid with one of the eccentric bearings 18 for the doffer supporting rollers 1d. The arms 55 and 55 and their shaft constitute, a rigid lever. "When the hand lever 20 is operated in associating the dofi'er with the spinning frame, the cable 42 will be automatically moved into driving engagement with the driving sheave 52. V p j The forward end of the shaft 51 carries a bevel gear 61 which meshes with a similar gear 62 upon the end of a shaft mounted in the bearing bracket 50, the opposite end of the last mentioned shaft having thereon a bevel pinion 63 meshing with a gear 64 which is loosely mounted upon the lower,

end of a vertical shaft 65 running in bearings 66 upon one of the frame sides 10. The upper end of the shaft 65 has fixed thereon a bevel pinion 67 meshing with a pinion upon a horizontal stub shaft 68. The

latter shaft has a pinion 69 which meshes with a gear-wheel 70 fixed upon the main actuating shaft 71 on the machine. The stub shaft 68 may have its forward end squared, or otherwise suitably shaped, to

be engaged by a hand crank so that the machine may be driven by handin bringing the parts to their normal starting position. The main actuating shaft 71 has fixed on its rear end a cam disk 72 upon one side of which is a roller stud 7 3 and an arcuate portion 74: arranged to engage with slots 7 5 and recesses 76 respectively in a starwheel 77 which is fixed upon a shaft 78 mounted in the crosspiece 13. A toothed propelling wheel 79 also fixed upon the shaft 78 engages with rack teeth 80 formed upon the lower edge of the guide rail 15 upon which the dofi'er is supported, and said toothed wheel is arranged to be given a series of intermittent rotations through the connection just described. A vertical shaft 81 has at its lower end a bevel pinion 82 meshing with'a bevel gear 83 on the shaft 78. The upper end of the shaft 81 has a pinion 8-]: which meshes with a gear 85 rotatable on the lower end of a vertical shaft 86, to be later described. A collar 87 is slidably but .nonrotatably mounted on the shaft 86 above the gear 85 has a clutch engagement with said gear 85, and the-collar being pressed downwardly by a coiled spring 88. When the collar is raised the shaft 81 may be rotated without moving the shaft 86, as will be later explained. The general operating mechanism of the machine is substantially similar to that shown in our co-pending application Serial No. 7

621,817, filed April 15, 1911 and need not here be described in detaiL' Briefly, this mechanism comprises a doifer head 89 fixed on the upper end of a vertical.reciprocatory rod 90 which is moved by a lever 91 connected thereto by a link 92. A lever 93 rigid with the lever 91 is connected to a crankpin on the gear wheel 70 by means of a link 96%. Thebobbin seater 95 is yieldably mounted on a vertically slidable rod 96 having its lower end yieldably connected to the'lever 91. A lever 97 for rocking a shaft to be later described is arranged to be operated by a cam (not shown) on the rear side of the gear wheel 70. Said cam also reciprocates a link 98 connected to a bell-crank lever 99 which opens and closes the dofl'erhead. The thread severing means 100 is mounted on a horizontal slide 101 (Fig. 3) which is operated by a lever 102 connected theretoby a link 103.

The magazine for the empty bobbins is carried by a pair of vertical standards 106 rising from the table 12. Uponthe upper ends of these standards is fixed a pair of brackets 107 which carry a horizontal support 108 upon which the bobbin magazine is arranged'to travel. The magazine proper The bobbins mounted in the lower portion of the magazine and transversely thereof, said plates having arcuate recesses at opposite sides thereof so formed that when the plates are slidden into proper position the recesses will coincide with the tubes 113 and permit the bobbins in said tubes to escape. One of the latch-plates is provided for every two rows of the bobbin tubes 113, there being in the present instance twenty-four rows of five tubes each in the magazine. The rear,

- forward ends of the latchplates 114 and projecting some distance below said latchplates. These ends of the crank members are arranged to be engaged by a stationary cam-plate, to be presently described, for the purpose of drawing the successive latchplates forwardly to release the bobbins from the magazine.

A plurality of brackets 121 project forwardly from the magazine and carry at their lower sides a pair of angular guide rails 122 running longitudinally of the magazine, said rails traveling in guideways 123 formed in the support 108. The rear one of the guide rails has rack teeth formed thereon, which teeth are arranged to be engaged by a pinion 124 fixed upon the upper end of the vertical shaft 86 which runs in a bearing 125 in the support 108. The'shaft 86 is given a series of partial rotations during the operation of the machine to advance the magazine step by step. When the magazine reaches the end of its travel the clutch collar 87 is lifted to disengage it from the gear 85, when the magazine may be pushed back on its guide, the shaft 81 rotating idly.

Beneath the magazine is positioned a donning tube 128 having its upper end widened and flattened to extend transversely beneath the magazine. The lower portion of the donning tube is mounted upon a bracket 129 carried by one of the standards 106 and the upper portion of said tube is secured to the magazine support 108. At the rear edge of the upper end of the tube is an anti-friction roller 130 upon which the rear edge of the magazine rests. A plate 131 extends laterally from the upper edge of the donning tube in a direction opposite to the direction of travel of the magazine, said plate being 6 adapted to prevent the bobbins in the spaces released by the latch-plates 114 from falling before they reach the donning tube. To the forward edge of the plate 131 is secured a cam-plate 132, along the forward edge of which the ends of the crank members 119 ride to draw the latch-plates 114 forwardly and release two rows of bobbins at a time.

Referring to Fig. 5, it will be seen that the upper end of the donning tube extends at an angle with reference to the transverse rows of bobbin tubes in the magazine; therefore, as the magazine is advanced the bobbins in any particular row will drop successively into the donning tube. A stop-plate 133 extends through a slot in the upper portion of the donning tube, said plate being fixed to a pair of bell-crank levers 134 pivoted to lugs on said donning tube. Said bell-crank levers are connected by a link 135 for a simultaneous movement. The forward one of said levers is fixed upon the upper end of a vertical rock-shaft 136, the lower end of said shaft being mounted in the bracket 129. Fixed upon the extreme lower end of said shaft is a stop member 137 arranged to extend through a slot in the lower portion of the donning tube to obstruct a falling bobbin therein. The parts are so arranged that when the stop plate 133 is projected into the donning tube the stop member 137 will be drawn therefrom and vice-versa. The shaft 136 is arranged to be rocked by means of a crank-arm 138 thereon, which is connected by a link 139 to a crank-arm 140 fixed upon the upper end of a vertical rock-shaft 141, which has its ends mounted in the bracket 129 and a lug 142 upon the standard 106 respectively; the lower end of said shaft has fixed thereon a crank-arm 143 which is rocked by means of the lever 97 previously described. The rockshaft 141 has a sleeve 144 rotatably mounted thereon and upon the upper end of this sleeve is an arm 145 having an angular end adapted to enter the donning tube and act as a stop for the bobbins therein; a coiled spring 146 tends to throw said arm toward the donning tube. The lower end of the sleeve 144 has thereon an angular arm 147" which is arranged to be engaged by a projection 148 carried by the link 103 of the reciprocable shearing mechanism for the purpose of rotating the sleeve and thereby withdrawing the projection on the upper arm 145 from the donning tube.
